Tanner's External Verification Interface (EVI) provides an interface for users of Mentor Graphics’ Calibre® tool suite, to use L-Edit and S-Edit for layout and schematic capture. When used in conjunction with the Calibre RVE product, you can view Calibre DRC errors, LVS results, and PEX parasitics in L-Edit and S-Edit. EVI is also compatible with Calibre Interactive, which allows users to run DRC & LVS on L-Edit and S-Edit designs from within Calibre Interactive.
